you can fit a bigger amp under the drivers seat than you can the passenger seat. the seats come out very easily, thanks to the door set up. 4 bolts and a couple of plugs for the airbag sensors. after the seats are out you can pull the console out. you have to be careful with it though, it can get tricky up under the dash mounted buttons. the door sills come off easily, just lift and pull, and then you can take off the kick panels, if needed. the drivers side footrest pulls straight out, and each kick panel has a plastic nut you unscrew, and just push back on later. I was amazed at how easy and quickly you can strip the interior of these trucks. this is what I did with mine......
stereo finally done
